10 trolling the supply of pressure fluid to the liquid are dispensed with, and with these objects in view myinvention consists in producing the pressure within the receptacle itself from suitable chemicals so that a chamber containing a pressure fluid is dispensed with.

For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawing in which the same reference characters have been used in all the views to indicate` corresponding` parts. `In said drawing, u

Fig. 1, is a sectional elevation showingV the receptacle containing the liquid,

\ 1 Fig. 2, is a sectional elevation showing the container' for the chemical -or chemicals adapted to produce the pressure gas, j

Fig. 3, is a sectional elevation showing the head to be fixed to the receptacle shown in Fig. 1, and j i Fig. 4, is a sectional view taken on the line Invthe example shown in the figures, the

apparatus 'comprises a receptacle 1 which is fpreferably made from aluminum and hasa` r capacity of say `1/l llter, the receptacle hav-` ingpreferably a flat-oval cross-section for convenience in handling the same.` At its top theV receptacle carries an internally screw threaded ring or cylinder 2 for filling the liquid into the receptacle, and the said ring is j formed at its bottom end with an inwardly di- A"rected flange 4- leavinga circular opening 3.

Near-its top end thesaid ring is provided" about its circumference with holes 5.

, The chemicals from which the pressure gas is produced are confined within a small cylin dricalbox Gmade from aluminum and formed atits top with a flange 7, thesaid box and flange fittingrespe'ctively in the circular openl ing 3 and on the flange 4l, the box 6 when placed with its Aflange on the flange t projecting into the receptacle 1. At its top and bot` tom the box 6 is closed by means of thin diaphragms 27 by means of which the access of the liquid from the receptacle 1 to the Cil 159,850, and in Germany January 30, 1326. l

chemical is prevented, the said diaphragms consisting of a suitable material such as cellophane, which can be readily broken.

j IThe head of the spray consists of ablo'ck 8 made from a suitable material such as aluminum, which block is formed with an axial bore flaring outwardly at its bottom end, and the block'is made integral with a nipple 12 the axial bore of which communicates with the .axial bore of the block 8. At its bottoln the head 8 is formed with an externally sc rewthreaded cylindrical portion 9 adapted to be screwed `into the internally screw-threaded cylinder or, ring 2. Above the said screw threaded portion the head is provided with a flange 28 carrying a suitable packing ring 25 adapted, when screwing the head into the Vring 2, to engage the top face of thereceptacle f1 and to provide an airtight closure. Below the flange the ycylindrical portion 9 is formed with a neck 29 and radial bores 24corrcsp`onding in position to the bores 5.

Within the axial bore of the head 8 there is a' conical valve 1.0 the stem of which projects upwardly beyond the top of the head and carries a cap-shaped button 18. `The valve cone 10 qis provided with a jacket 13 in the form of arubberhose fiXe'd to the bottom face of the valve cone by means of a buttondascrewed toa pin 15.

The top end of l the saidhose is bent downwardly and around the top part of the head 8,and it is held in position by means of a cap 17 placed thereon and having an axial bore for the passage of the valve stem therethrough. j i

. The nipple 12 carries a flexible tube 19 preferably made.` from thick and elastic rubber and formed at its rear en'd with a conical flange 20. adapted, incase of leakage to protect the hand of the operator as against the liquid. To the outer end of theflexible tube 19 a nozzle 22 is fixed by means of a nipple 21, the said nozzle being made from a suitable material such as porcelain, vulcanite, or bakehte. Preferably the said nozzle 1s formed with external longitudinal ribs and grooves, and it is formed with longitudinal and transverse bores 23` forthe discharge of the liquid.

Symmetlially of the nipple 12 a nipple 11 is formed onthe head 8, which however j is .not provided with a longitudinal bore, the

object of the said nipple 11 being `tofacilitate thehandling of the head. The rubber hose 13 has the function to provide a tight seat forthe valve cone, and in additiomjit` 'f with the liquid toy be directed upon the body,

a box 6 containing -a suitabley chemical such as amixture of tartaric acid and bicarbonate of soda is placed into the receptacle 1 through vtheopening Sso that its flange 7 bears on the flange 4, and the head ,8 is screwed into the ring 2. Newv the receptacle 1 is perfectly closed. by the packing4 ring 25 being pressed .on the top 'faceofy the receptacle; If it is `desired, to use ythe receptacle, kthe valve- 10 is pushed downwardly, sothat the button 14 passes into the box 6 and presses the lchemical .confined therein into the liquid contained in thereceptacle 1.7' After a few minutes the liquidfis saturated with carbonic acid, and

there is 7sufiicient pressure within the receptacle. New the flexible tube 19 is yput on the nipple 12, the receptacle 1 is turned upside down, land the nozzle 21.is passed into the cavity of the body to be irrigated. If now the Apuslr'loutton ,18 is againdepressed, the-valve 30V lOis opened, and theliquid is forced through the bores 5, the neck 29, the bores24, the

axial'boreof the fhead'S, the nipple 12, the

vtube/19, and the nozzle, the. velocity and pressure ,of the liquid discharged through the ynozzle beingregulated by more or less opening the valve. g

.Itwill eunderstood that other chemicals Amay' be usedk for producing the gas, and that insomecasesone-of-the components is dissolvedfinthe liquid, ,whilethe otherone is conned in theboxfl. .Thus I am enabled to usein part liquidreagents, such for example :jasdisinfectlng woodfvinegar. When using Ybicarbonate of-Qsofdafandwtartaric acid forv producingthe'pressure gas, I` may use the .tartaric aci-d 1n. excess in order to impart a slight disinfecting actionto the liquid. If

a more active disinfectingfproperty is desired I- addspecic disinfecting media to the mixture of chemicals.

l s.' developing the gas within'the receptacle 1 the liquid .takes .up` numerous small gas ,bubblespso.that its active surface is materially'increased, vand a comparatively small amountof liquid. is sufficient for producing n the desired effect on .the human body.v

.From the foregoing description it will be V,understood that the complete apparatus is A, .compara-tively small, because no chamberfor l.. Vstoring the'y pressure fluid is needed. This is f' inapo'rtkant particularly in such cases in which theappa-ratus isfto 'be carried inthe pocket )o ffthe physician visiting his patients. By

65,5placingathechemicals in a removable box 6k chemicals of diiferent character may be used according to the elfect aimed at by the physician. The box containing the chemicals may be put into the receptacle and the whole apparatus be prepared for use, so that it can be used at 'any time when needed.

While in describing the invention reference has been made to a particular example embodying the same I wish it to be under stood that my invention is not limited to the construction shown in the drawing, and that various changes may be made in the general arrangement of the apparatus and the construction of its parts without departing from the invention.
